Point of possible perception? Point of actual perception? Point of response? Skid tire, scuff tire, metal marks or all three? Weather? Lighting? Trees and shrubs? Parked vehicles, fences, buildings, or other obstructions? Investigating any accident scene is no doubt a complex task. Determining the accurate answers to these questions from participants, and from non-participants as well, can be even harder. With this book, you will not have to spend fruitless hours re-creating the accident over and over again because of lack of notes, inadequate interviews, or blurry photographs. Instead, you will have everything organized from the start in a clear, cohesive story--fully documented with all the witness statements, notes, photographs, and reports ever needed. Discover how you can use this valuable guide to save time without sacrificing accuracy; it is, simply, the only book you will ever need to fully report any automobile accident scene.
